Thermal Oxidizer - Regenerative Catalytic Oxidizer (RCO)

Regenerative Catalytic Oxidizer (RCO)

In some applications, the use of a catalyst helps allow oxidation at somewhat reduced temperatures. As an example, the thermal ignition temperature of carbon monoxide is at 609°C Carbon monoxide. However, by utilizing a suitable oxidation catalyst, the ignition temperature can be reduced to around 200°C. This can result in even lower operating costs compared to a Regenerative Thermal Oxidizer. Most systems operate within the 500F (260°C) to 1000F (540°C) degree range. Some systems are designed to operate both as Regenerative Catalytic Systems and Regenerative Thermal Oxdizers. When these systems are used special design considerations are utilized to reduce the probability of overheating (dilution of inlet gas or recycling), these high temperatures would deactivate the catalyst, e.g. by sintering of the active material Sintering.
